Comparing High-End AV Receivers: Making Sense of Modern Home Theater Brains

When setting up a home theater system in 2024, choosing the right AV receiver is crucial - it's literally the brain of your entire setup. Today, we're comparing two popular options: the entry-level JBL MA710 ($679) and the more premium Onkyo TX-RZ50 ($1,399). Both entered the market in late 2022 and have established solid reputations, but they serve different needs and budgets.

Understanding Modern AV Receivers

Before diving into specifics, let's understand what makes current AV receivers different from models just a few years ago. The biggest changes revolve around HDMI 2.1 support (enabling features like 8K video and enhanced gaming capabilities) and more sophisticated room correction technology. These receivers also handle object-based surround sound formats like Dolby Atmos, which places sound in a three-dimensional space rather than just around you.

Configuration and Channel Counts

The JBL MA710 offers a 7.2-channel configuration, meaning it can power seven speakers and two subwoofers. This setup works well for most home theaters, supporting either a traditional 7.2 surround setup or a 5.1.2 Dolby Atmos configuration (where the ".2" at the end refers to two height channels for overhead effects).

The Onkyo TX-RZ50 steps up to 9.2 channels, allowing for more complex speaker arrangements. It can handle up to a 7.2.4 Atmos setup with an external amplifier, meaning you get four overhead speakers instead of two. This might seem like overkill, but in larger rooms, those extra height channels make a noticeable difference in creating a more immersive sound bubble.

Power and Performance

Power specifications can be confusing, but they matter for driving speakers effectively. The JBL delivers 110 watts per channel into 8 ohms, which is plenty for most speakers in medium-sized rooms. The Onkyo boasts 250 watts per channel and carries THX certification, suggesting more headroom for demanding speakers or larger spaces.

In real-world use, both receivers handle movie soundtracks well, but the Onkyo's extra power becomes noticeable during dynamic peaks - think explosion scenes or orchestral crescendos. This overhead means less strain on the amplifier and cleaner sound at higher volumes.

Room Correction Technology

This is where we see one of the biggest differences between these units. The JBL uses their proprietary EZ Set EQ system, which is straightforward but basic. It measures your room's acoustics and adjusts speaker levels and distances accordingly.

The Onkyo implements Dirac Live, considered one of the best room correction systems available. It not only adjusts levels but also corrects for room reflections and standing waves that can muddy the sound. Having used both systems, I can say Dirac Live makes a notably bigger difference in improving overall sound quality, especially in challenging rooms.

Video Capabilities

Both receivers support 8K video passthrough and 4K/120Hz gaming features, which future-proofs them for upcoming video standards. The Onkyo offers slightly better gaming support with features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) on all HDMI inputs, while the JBL supports these features on select ports.

Connectivity and Streaming

Modern receivers need to handle both traditional and streaming sources well. Both units offer built-in Wi-Fi and Bluetooth, but the Onkyo adds features like Chromecast built-in and AirPlay 2. The JBL's streaming implementation is more basic but gets the job done through its companion app.

Value Proposition

The JBL MA710 represents excellent value for those building their first serious home theater or upgrading from an older receiver. Its feature set hits all the essential points for modern home theater, and the sound quality is impressive for the price point.

The Onkyo TX-RZ50 justifies its higher price through superior room correction, more channels, and additional features that matter to enthusiasts. If you're planning a more elaborate setup or want the best possible sound quality, the extra investment makes sense.

Real-World Performance

In day-to-day use, both receivers perform their core functions well. The JBL's simpler interface might actually be preferable for less tech-savvy users. The Onkyo's additional features and setup options can be overwhelming at first but reward those willing to dive deep into optimization.

For movie watching, both deliver engaging experiences. The JBL handles standard surround sound formats beautifully, while the Onkyo's additional processing power and superior room correction create a more refined and precise soundstage.

How to Decide

Choose the JBL MA710 if:

• You're working with a stricter budget
• Your room is small to medium-sized
• You want a simpler setup process
• A 7.2 or 5.1.2 speaker configuration meets your needs

Choose the Onkyo TX-RZ50 if:

• You have a larger room or challenging acoustics
• You want the best possible sound quality
• You plan to expand to a more complex speaker setup
• Advanced features like Dirac Live matter to you

Looking Forward

Both receivers are relatively current models with modern features, but technology moves quickly. If you're considering either unit, you're getting solid 8K support and gaming features that should remain relevant for years. The Onkyo's more advanced room correction and processing power might give it a longer useful life for enthusiasts.

In the end, both the JBL MA710 and Onkyo TX-RZ50 are capable receivers that serve their target audiences well. The JBL offers tremendous value for those entering the world of serious home theater, while the Onkyo provides the features and performance that enthusiasts crave. Your choice should align with your space, budget, and how deep you want to dive into home theater optimization.
